AM2432: When using USB dfu-util load FW, how to tell whether the AM243x MCU is HS-SE converted or not?

Hello TI team, 


We have been leveraging the SoC ID reported on UART console when working on keywriter for the UART boot mode case. But when we move to USB boot mode, this information is not available any more. 

Is there a way that allow us to get the same SoC ID output at USB boot mode similar to UART boot mode case?


Thanks, 
Hong

    Hello,

    Please refer the below logs for retrieving the SoC ID over USB DFU:

    ❯ dfu-util -a SocId -U socid.bin
dfu-util 0.11
